Question

Examine the following titration curves for the next 2 questions Titration (a) Titration (c) Titration (d) Vokume of titrant, mL volume of titrant, mL 44. Which one ofthe titration curves comesponds to the titration ofa weak acid (in flask with strong base (in buret)? B. b he following best characterizes the solution in the flask at the ration curve (d). Which one 45. Consider equivalence point of the titration? (c) a solution of a weak acid (a) a solution of a strong acid (d) a solution of a weak base (b) a solution of a strong base (e) a neutral solution

Explanation / Answer

Question 44.

titration of weak acid --> must have an acidic pH, i.e. pH < 7,

ignore B and D

since weak acid --> must have a buffer reagion, so choose A between a and c

Question 45.

solution in the equivlanece point:

This is clearly a strong base initially, and the titratn is strong acid

so this will be a neutral solution in equivalence
